UK employers refused to increase salaries because they had unlimited supply of cheap labour from Eastern Europe, they treated them like shit but they still came and worked for them. Well the end result is those same working class British who they refused to pay more eventually voted Brexit. Now the UK employers are super desperate for staff because there is no more cheap labour for them to take advantage off. And wages are rising faster because the workers are in charge now.
